亲爱的8老师，
我2个星期前从美国用PRIORTY MAIL给父母寄面签材料，They still have not received!! Their interview date is in middle of August and I am real worry!! Some of the documents are original, If they are get lost, Its going to be very difficult to retain them again!! I have called the post office to ask them how I could located my mail, Beacuse the tracking number only shows it reach to NY, They told me that once the mail leave US, There is no way to track it!
My dad aslo has called the China post and he got the same information I got!!
I am about the cry and do not know what to do!!
Please please advice me what I am suppose to do at this point!
跪谢！！
